EU Citizenship by Descent 2026: Which Countries, Who Qualifies & How

In short

EU citizenship by descent means obtaining or confirming a member state’s nationality through qualifying ancestry, not buying an EU passport. Ireland’s Foreign Births Register costs €278 per adult and €153 per child; some German restoration routes are free. Eligibility depends on the country, the ancestral chain and when citizenship passed between generations.

Who qualifies for EU citizenship by descent?

You qualify only if a particular EU member state’s nationality law connects you to a citizen ancestor or provides a restoration route for your family’s circumstances.

There is no EU-wide ancestry application. Citizenship of a member state brings EU citizenship with it, but each country determines who its nationals are. The European Commission explains this distinction on its EU citizenship pages.

The essential question is not simply, “Was my ancestor European?” It is: “Was that ancestor a citizen, and did citizenship reach the next generation under the law applying at the time?”

Birthplace alone may not answer that question. Borders changed; emigrants naturalised abroad; and historical laws sometimes treated mothers, unmarried fathers and adopted children differently.

For Ireland, the decisive distinction is often between an Irish-born parent, an Irish-born grandparent, and an ancestor further back. A great-grandparent does not ordinarily provide a standalone entitlement: the intervening parent generally needed to have become Irish through registration before the applicant’s birth. See the Department of Foreign Affairs’ citizenship guidance.

Germany also has a potentially important overseas-generation restriction. Under section 4(4) of the Nationality Act, transmission can be restricted where the German parent was themselves born abroad after 31 December 1999 and habitually lives abroad. Exceptions apply, including a mechanism involving an application to register the child’s birth within one year. The exact family circumstances matter; consult the official Nationality Act.

Italy warrants particular caution. Under the amended framework, relevant exceptions include having a parent or grandparent who held exclusively Italian citizenship, or a parent who met the specified two-year continuous residence condition in Italy before the applicant’s birth or adoption. Transitional protections also exist. The Italian Ministry of Foreign Affairs should be the starting point, rather than eligibility summaries written before the reforms.

How much does EU citizenship by descent cost?

The cost depends on the national route, the number and ages of applicants, and the documentary work required; there is no single European citizenship-by-descent fee.

Government application fees are only one component. Civil-status certificates, legalisation, translations, delivery and the eventual passport are separate. Some applicants need only a small document set; others must reconstruct several generations across different jurisdictions.

The table below gives the official application and passport fee lines that can be stated confidently for the specified routes. It is not a universal EU tariff: fees outside this scope, local-currency equivalents and document-specific charges must be confirmed with the relevant authority.

For comparison, “family of four” means two adults and two children under 18, each independently eligible and each needing the service shown.

Irish fees are published by the Department of Foreign Affairs for Foreign Births Registration and the Passport Service. German fee exemptions are explained in the Federal Office of Administration’s citizenship guidance. Italian missions publish the consular recognition charge and payment instructions.

An ancestry application is not an investment programme. The routes discussed here do not require a property purchase or investment contribution. Equally, a paid genealogical report or legal opinion does not replace official evidence or bind a nationality authority.

How long does citizenship by descent take, and must you live in Europe?

Processing can take months or longer, while qualifying recognition and registration routes generally do not require you to relocate to Europe.

Three separate periods determine the practical timetable:

1. Document preparation: obtaining records, correcting discrepancies and completing any required authentication.
2. Nationality processing: examination by the competent registry, consulate or nationality authority.
3. Passport processing: a separate application after citizenship is established or acquired.

Ireland’s Foreign Births Register has published an indicative processing period of approximately nine months for complete applications. This is an administrative estimate, not a statutory deadline or a guarantee; check the current official registration guidance before making plans.

There is no equally useful single German or Italian figure. The route, authority, archival enquiries and application completeness can change the timetable substantially. Where the responsible authority does not publish a dependable current estimate, a precise number of months would be misleading.

Residence requirements also need careful language. For the Irish Foreign Births Register and the German overseas procedures described here, there is ordinarily no annual stay-day quota comparable to a residence-by-investment programme. Attending a consular appointment or providing identity evidence is not the same as having to establish residence.

Italy’s ancestral two-year residence exception concerns a qualifying parent’s history under the amended law; it should not be mistaken for a universal requirement that every applicant live in Italy for two years. Applying through an Italian municipality raises separate residence and procedural questions.

Some deadlines matter more than the queue. Germany’s section 5 declaration route addresses specified discriminatory exclusions affecting people born after 23 May 1949 and their descendants. Its statutory declaration window runs for 10 years from 20 August 2021. Applicants should confirm the applicable deadline and submission requirements directly with the Federal Office of Administration rather than assume an unfinished document search preserves eligibility.

How do you apply for citizenship by descent?

You apply by identifying the correct legal route, proving every relevant family link and submitting the prescribed evidence to the competent national authority.

A disciplined eligibility audit should precede expensive document orders.

First, establish the nationality event. Was your parent already a citizen when you were born? Did an ancestor lose nationality before the next generation’s birth? Are you seeking confirmation of existing citizenship, registration that creates citizenship, or restoration under a remedial law?

Those distinctions determine both evidence and legal effect. Irish Foreign Births Registration, for example, should not be treated as merely printing proof of a citizenship you necessarily held from birth.

Second, build a dated family chain. Record each relevant birth, marriage, adoption, naturalisation and death. Include original names and later changes. The most important document is sometimes an ancestor’s foreign naturalisation record, because its date can establish whether citizenship transmission was interrupted.

Third, use the authority’s current checklist. Common requirements include:

• Full civil birth records linking each generation.
• Marriage or other records explaining changes of name.
• Evidence of the ancestor’s nationality.
• Naturalisation or non-naturalisation evidence where relevant.
• The applicant’s identity and address documents.
• Photographs, witnesses, certified copies or original documents as prescribed.

This is a working checklist, not a substitute for the country-specific one.

Fourth, check authentication before paying for it. Not every foreign certificate needs an apostille. Regulation (EU) 2016/1191 removes legalisation requirements for certain public documents circulating between EU member states and provides multilingual standard forms in specified circumstances. Its scope is limited: simplifying document authenticity does not require an authority to recognise every legal effect of the underlying document.

Finally, submit a consistent file and retain a complete copy. Unexplained differences in dates, spellings or parentage can trigger enquiries. Corrections should follow the issuing authority’s lawful process; applicants should not alter records themselves.

A commercial family tree can guide research. It is not a substitute for civil-status evidence. Likewise, a consumer DNA result does not by itself establish citizenship or satisfy the prescribed proof of legal parentage.

Can your children and spouse get citizenship, and can you keep your existing passport?

Children may have their own citizenship entitlement, but spouses do not automatically acquire nationality through your ancestry application, and dual citizenship must be checked under both countries’ laws.

“Family application” is therefore a potentially misleading label. Shared documents may reduce duplication, but each person still needs a legal basis.

Ireland illustrates why timing matters. Someone who becomes Irish through the Foreign Births Register generally needs to be registered before their child is born to transmit the relevant entitlement to that foreign-born child. If a pregnancy makes timing urgent, consult the Department of Foreign Affairs’ official procedure promptly; ordinary processing estimates should not be treated as assurances.

Germany’s declaration and persecution-restoration provisions can extend to descendants, but eligibility remains provision-specific. Italy’s amended rules make it particularly unsafe to assume that recognition for a parent automatically settles every child’s position.

A spouse’s options belong in a separate assessment. Citizenship through marriage may involve residence, language, duration-of-marriage or other conditions. EU family residence rights are also different from nationality: accompanying an EU-citizen spouse does not itself produce an EU passport.

On dual nationality, Ireland permits dual citizenship, while Germany’s current nationality framework generally permits multiple nationality. Nevertheless, the country whose passport you already hold may restrict voluntary acquisition of another citizenship or impose notification requirements. Confirmation of citizenship held from birth can also have different consequences from a new acquisition.

The practical sequence is therefore clear: establish each person’s eligibility, determine when citizenship takes effect, check the consequences for existing nationality, and only then apply for passports. An ancestral connection starts the enquiry; the governing law and documentary chain decide the result.

Step-by-step timeline

A descent claim is best managed as a sequence of evidence checks, not a countdown to a passport. Establish which law applies before ordering an entire family archive: some applicants are documenting citizenship already held, while others must complete a registration or acquisition procedure.

There is no meaningful EU-wide processing average. The stages below distinguish work within your control from decisions that depend on registries, consulates or nationality authorities. Current processing estimates should always be confirmed with the office handling the case.

The most common practical delays arise from missing records, inconsistent identities and incomplete evidence about an ancestor’s naturalisation. An application can also stall because a document is genuine but supplied in the wrong format. Check certificate type, authentication and translation instructions before commissioning work.

Tax and stay requirements

Citizenship, immigration residence and tax residence are separate questions. Recognition of nationality should not be treated as either a tax-planning product or evidence that you have moved your tax residence.

The European Commission’s Your Europe guidance explains that there are no EU-wide rules determining how cross-border personal income is taxed. Spending more than six months in a country commonly points towards tax residence, but that is guidance rather than a universal statutory test. A permanent home, personal and economic ties, domestic legislation and an applicable tax treaty can change the outcome.

A newly recognised citizen who remains abroad should therefore assess their actual circumstances rather than assume that a passport creates — or eliminates — tax liability. Income arising in a country, property ownership, business activity and inheritance can create obligations independently of residence. Citizenship-based obligations under another country’s laws may also remain relevant.

For physical presence, distinguish a genuine descent-recognition procedure from preferential naturalisation based on ancestry. Do not assume that every route described informally as “citizenship by descent” is available without relocation. Ireland’s Foreign Births Register provides a mechanism for eligible applicants abroad; a residence-based naturalisation application is a different legal process.

There is likewise no EU-wide annual stay requirement for maintaining nationality. Check the relevant country’s rules on acquisition, retention and loss, particularly where the case involves an unusual historical provision or acquisition of another nationality.

Finally, passport renewal is not citizenship renewal. A replacement passport concerns the travel document; it does not ordinarily require the holder to prove eligibility for nationality afresh. Identity evidence, civil-registration updates and documentary requirements may nevertheless apply. Before relocating, consider separately whether your household’s residence, employment and tax arrangements need to be changed.

How it compares

For someone investigating European ancestry, the closest realistic alternatives are ordinary residence-based naturalisation and ancestry-linked preferential naturalisation. The latter can be relevant where family origins do not establish citizenship directly but support a separate statutory route.

Direct descent suits applicants whose documentary record supports the required legal chain. Ordinary naturalisation suits those who genuinely intend to settle and can qualify for lawful residence independently. Preferential naturalisation merits investigation when ancestry is relevant but insufficient for recognition. Germany’s Federal Office of Administration, for example, distinguishes several nationality procedures, including routes addressing historical persecution or discriminatory rules; these should not be confused with ordinary descent claims.

The useful comparison is not simply which route appears fastest. It is which route remains legally available after the family history, current legislation and applicant’s willingness to relocate have been tested.

Common mistakes and what they cost

Ordering everything before confirming the legal route. A substantial archive does not cure ineligibility. Establish which ancestor matters and which intervening events must be evidenced before paying for certificates, translations and authentication. Otherwise, expenditure may produce documents that the relevant authority never needs.

Relying on an old eligibility checklist. Nationality legislation can change materially. Italy’s Ministry of Foreign Affairs now explains descent rules in light of legislative changes introduced in 2025. Older summaries may therefore describe a route that is no longer available on the same terms. The cost is not merely an unsuccessful filing: families may make relocation or education plans around an assumption that proves wrong.

Treating a surname discrepancy as harmless. Anglicised names, inconsistent dates and differing places of birth can leave an authority unable to connect records confidently. Do not alter documents yourself or commission unnecessary corrections without instructions. Ask whether the case requires amended civil records, additional evidence or another recognised explanation.

Confusing an ancestor’s emigration with naturalisation. Moving abroad and acquiring another nationality are different events. Where nationality transmission depends on historical loss rules, the relevant evidence may be the date and legal effect of naturalisation — not a passenger list or census entry. Missing that distinction can undermine the entire chain.

Paying for the wrong document service. Translation, notarisation, legalisation and an apostille perform different functions. The receiving authority’s instructions govern what is needed. An expensive notarised copy may still be unacceptable where a particular civil-registry certificate is required.

Making irreversible plans before recognition. Avoid treating a pending claim as permission to live or work in the EU. Non-refundable travel, housing commitments and school arrangements create financial exposure if recognition takes longer than expected or is refused. Preserve an independent lawful basis for any intended stay.

Poland: Confirmation of citizenship

Poland’s approach is to ‘confirm’ that an applicant has been a Polish citizen since birth, rather than granting new citizenship. Eligibility generally depends on an ancestor who was a resident or citizen after Poland became an independent state in 1918, with the key period starting after 1920.

Polish nationality law, particularly the Acts of 1920 and 1951, is complex. An ancestor may have lost citizenship through events such as serving in a foreign army, holding public office in another country, or, before 1951, through marriage. There is no generational limit, but the chain of citizenship must be proven to have remained legally intact according to the laws applicable at the time. Applications are typically submitted to the Masovian Provincial Office in Warsaw.

Portugal: Ancestry routes

Portugal provides two main pathways based on ancestry.

The first route is for the children or grandchildren of Portuguese citizens. While children can often claim citizenship directly, grandchildren must demonstrate an ‘effective connection’ to the Portuguese community. This connection requirement often includes proving A2-level proficiency in the Portuguese language.

Portugal no longer accepts new applications under the Sephardic descent route. The 2026 Nationality Law closed new applications; applications already submitted before 19 May 2026 are assessed under the former rules.

Frequently asked questions

Can a DNA test prove I qualify for EU citizenship by descent?

A commercial DNA ancestry result is not a substitute for the legal evidence required in a nationality application. Authorities assess the qualifying family relationship and the nationality law governing it, generally through civil and citizenship records. A DNA result may suggest where to research, but it does not establish that a particular ancestor held or transmitted citizenship.

Can I claim citizenship through my great-grandparents?

Possibly, but a great-grandparent’s nationality alone does not establish eligibility. The answer depends on the country, each generation’s legal position and any registration, retention or other applicable conditions. Work through the chain chronologically rather than counting generations in isolation. Current legislation matters, even where relatives successfully relied on the same ancestor in the past.

Does my parent have to apply before I can?

Not always; the answer depends on whether your parent already held citizenship or needed to acquire it through a separate procedure. Some claims require proof of an existing chain rather than consecutive applications. Under Ireland’s Foreign Births Register rules, where a parent’s citizenship derives from registration, registration before the child’s birth can be decisive.

What if my ancestor became a citizen of another country?

An ancestor’s naturalisation may affect your claim, but its consequences depend on the nationality law and dates involved. Obtain evidence of whether naturalisation occurred and when, then compare that event with the next generation’s birth and the applicable historical rules. Do not assume that today’s acceptance of dual nationality resolves an earlier loss of citizenship.

Can I use my cousin’s successful citizenship application?

Your cousin’s application can provide useful research leads, but it does not automatically establish your entitlement. Your branch may involve different birth dates, marriages, naturalisations or registration events. Ask the relevant authority whether it can reference documents already held in another file; do not assume that it will accept copies supplied by your cousin.

Can I apply if my family’s birth records were destroyed?

Missing records do not necessarily end a claim, but acceptable substitute evidence must be confirmed with the receiving authority. Begin by documenting searches through the relevant civil registry or archive. Depending on the jurisdiction and circumstances, further official evidence or a formal reconstruction process may be necessary. Informal family accounts cannot simply replace mandatory records.

Can I apply for two European citizenships through different ancestors?

You may have grounds to investigate two claims, but each must satisfy its own nationality law. Check retention and loss rules across all citizenships involved before proceeding, including your existing nationality. Documentary requirements and decisions remain separate. Recognition by one country does not oblige another country to accept the same legal reasoning or evidence.

Can I live anywhere in the EU once my citizenship is recognised?

As an EU citizen, you have free-movement rights, but residence in another member state remains subject to applicable conditions. Your Europe distinguishes residence rights by circumstances, including employment, study and economic inactivity. Registration, sufficient resources or comprehensive health insurance may be relevant. Recognition of citizenship does not remove every administrative requirement associated with moving.

Will I lose citizenship if I never renew my passport?

An expired passport does not ordinarily mean that citizenship has expired. Nationality status and the validity of a travel document are distinct matters. Nevertheless, check the relevant country’s retention and loss provisions rather than relying solely on passport possession. When renewing after a long gap, you may need updated identity documents or evidence of civil-status changes.

Can I pay extra to get a faster citizenship decision?

Do not assume that paying more will accelerate a nationality decision. Private expenditure can help organise research or obtain documents, but only the responsible authority can determine whether an official priority procedure exists and whether you qualify. Urgent passport arrangements, where offered, are separate from establishing citizenship and should not be mistaken for expedited recognition.

Do I need to speak the language?

For the descent-based routes in Ireland, Italy and Poland, there is generally no language requirement. Portugal, however, requires grandchildren of Portuguese citizens to demonstrate an A2 level of proficiency in Portuguese as part of proving an ‘effective connection’ to the country.

What is the ‘1948 Rule’ for Italian citizenship?

Before 1 January 1948, Italian law only allowed men to pass citizenship to their children. This means if your direct line of descent runs through a female ancestor whose child (the next person in your line) was born before that date, you cannot apply through the standard consular process. Instead, the claim must be filed in the Italian courts. These ‘1948 cases’ are a distinct legal route and typically require an Italian attorney, but have a high success rate.

What is a realistic total cost for a citizenship by descent application?

While official government fees are often less than €500, they are only a small part of the total expense. A more realistic budget, including costs for professional genealogical research, obtaining certified records, apostilles, official translations and any legal representation, typically ranges from €5,000 to €15,000. The final amount depends on the complexity of your family history and the number of documents required.

Can my spouse get citizenship based on my application?

Your spouse cannot automatically claim citizenship through your ancestry. They must qualify for naturalisation through marriage, which is a separate process with its own requirements. These often include a minimum duration of marriage and may involve a language test. For example, spouses applying for Italian citizenship through marriage must typically demonstrate B1-level proficiency in the Italian language.
